GUARD; MEIVEBER. FOR.MQP HANDLES Application filed April 10,

This invention. relates to newand useful. improvements. in a guard member for mopheads. i

The invention has for an object the pro- 5 vision of a device of the class mentioned which is of simple durable construction, dependable in use and eifici'entin action, and which canbe manufactured and sold at a reasonable cost. v

The invention proposes the use of a stationary jaw with a base strip having a con: caved bottomand bearing, portions arranged to hold resilient ends each consistingofwire having an outer transverse central portion covered by a rubber tube and right angle arms directed inwards into the said bearing portions, and a movable jaw consisting of wire having a central transverse portion engageable in the concaved bottom of the base strip and right angle arms directed upwards between the central portions of the resilient ends and the ends of the base strip. The resilient ends may be modified with the addition of springs to increase their resilient action.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure Fig. 1 is a front elevational view of a mop head with guard members constructed according to this invention.

The reference numeral 10 indicates generallya mop handle which has supported on its lower end amop clamping member indicated generally by reference numeral 11 which is. provided with resilient ends indicated gener'ally by numeral 12. The clamping member consists: of a stationary aw 13, a movable jawl i'and clamping means15;

The-stationary jaw 13has abridge plate 16 with atop forward pressed semi-ring 17 and anadjacent rearward pressed semi-ring 18 both together'forming a complete ring encircling the'handle10, a bottom: strip portion 19-and a bottom forward pressed semi-ring 2 0' and an adjacent rear-ward pressed semiring 21both-together forming-a complete ring encircling thehandle 10. A bolt 22 is passed thru' the semi-ring17- and the handle 10 for fastening these; parts, together. The stationaryjaw' also has a base stripQl formed. with a coincaved bottom portion 25 and with beari'ng portions-26on opposite edges, said bearingportions being longit'udinal of the strip and. parallel. thereto, the strip 24 being integral with the bottom of'the strip 19.

The movable jaw 14' is formed from a wire having a. central transverse portion 27 and right. angle, arms 28 directed upwards. The clamping means 15 consists of aspring 29 co"- axially mounted on the handle 10 and acting between the top portion of the stationary jaw and lower portion of a lever 30, which lever is formed with a front bearing loop 31. encircling one ofthe turns of the spring. The lever 30 is provided with side ears 82 engagedby the free ends of the arms 28. As shown in Fig. 2' these ears extend partially around the. handle 10 so that the spring 29 attempts to pivot the lever 30 against the handle and thus holding the clamping means in a closed position.

The top" end ofthe lever may be moved out wards for ivoting the lever about the loop 31 and" initially-pressingthespring until the ears 32 pass a neutral line relative to the pivotal point of the lever, then the spring serves to urge the lever downwards and the clamping member may be moved to its open position as illustrated in Fig. 3. In this condition of the device a mop rag may be inserted between the stationary jaw 13 and the movable jaw 14. Each of the resilient ends 12 consists of a piece of wire having an outer transverse center portion 33 and right angle arms 34 directed inwards and engaging into the ends of the bearing portions 26. The central portion 33 of the wire is covered by rubber tubing 35. When the mop is being used and is accidentally hit against the wall of a room or against furniture during use the resilient ends do the striking and produce the least amount of damage since the rubber tubes absorb most of the shock. Friction is depended upon to maintain the engagement of the resilient ends in the bearing portions 26.

In the modified form of the device illustrated in Fig. 6, a resilient end 12' has been disclosed formed from a wire having an inner transverse central portion 36 connected with right angle arms 37 directed outwards and at their free ends turned together as indicated by numeral 38. A rubber tube 39 is engaged upon the outer portions of the arms 37 and serve to absorb shocks when struck against objects. The inner transverse central portion 36 passes thru an elongated opening 40 formed in the bridge plate 19 and a tension spring 41 acts between the central portion 36 and the bridge plate for normally urging the resilient member inwards while a second spring 42 acts between the central portion and the bridge plate for urging the resilient member outwards. These springs are of such tension that normally the central portion 36 assumes a position midway between the ends of the opening 40. This arrangement prevents accidental displacement of the resilient ends and in addition addsto their resilient qualities.

In the modified form of the device illustrated in Fig. 7, transverse center portion 33 is shown to form an unsymmetrical shape and is covered by rubber tubing 35. In Fig. 8 transverse center portion 33 is shown to be provided with a loop 33 so as to make a right angle arm 34 resilient and central portion 33 is partially covered by rubber tubing 35.

IVhile I have shown and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims. Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is 2-- V l. The combination with a mop head having a bottom strip portion, of a strip connected with said bottom strip and formed with hearing portions on opposite edges, said hearing portions being longitudinal of said strip and parallel thereto, a wire member having a transverse portion slightly spaced from the end of said strip and right angled co-extending arms at the ends of the transverse portion and extending into said bearing portions, and a rubber tube on said transverse portion.

2. The combination with a mop head having a bottom strip portion, of a strip connected with said bottom strip and formed with bearing portions on opposite edges, said bearing portions being longitudinal of said strip and parallel thereto, awire member having a transverse portion slightly spaced from the end of said strip, right angled co-extending arms at the ends of the transverse portion and extending into said bearing portions, a rubber tube on said transverse portion, a portion connecting the inner ends of said arms and extending thru a slot in said bottom strip portion, and resilient means for balancing said wire member with the portion on the inner ends of the arms substantially at the center of said slot.

In testimony whereof I have affixed my signature.
